Title: Peeling process for peaches tomatoes and potatoes - by steam heating under high press for short time and agitation
Inventor: KUNZ PAUL
IPC: A23N7/00
Filed: 1973-12-06
Abstract: Peeling process for tomatoes, peaches, etc., in which the layer immediately beneath the skin is heated with steam for a short time, is effected in a press. vessel. A flange holds a closing ring with the filling funnel. Another flange, at the lowest part of the base, holds the opening and closing mechanism. For use, the washing fruits are introduced through the funnel and the closing mechanism is operated; press. exerted on the piston forced the cover against the closing ring and at the same time fluid under press. enters through the orifices. The vessel is rotated between the bearings and the fruits are continuously agitated so that heating is uniform. A press. of 10 atmos. is maintained as long as is necessary to bring the temp. just below the skins to 180 degrees C; the time varies between 5 and 20 seconds, accord-ing to the nature of the skins. The superheated layer under the skin commences to boil and the skin is forced off; the simultaneous rotation of the vessel causes the skins to be removed uniformly over the whole surface of each fruit. Relatively tender fruits and vegetables can be peeled per-fectly and without undergoing any alteration in their quality.

Title: Flower bench with two-sectioned box - has flower part standing in water section without direct contact to soil
Inventor: DELLIN HEINZ
IPC: A01G31/00
Filed: 1974-01-11
Abstract: The water required for the plants' growth flows through the water section to a height of approximately three centimetres. The water rises from the water section through foam ducts into the flower box over it, with the ends of the duct buried in the soil and the plant roots. The required water depth is indicated by a red ring. The flower arrangement may be enhanced at night by means of a fluorescent strip lamp covered by coloured foil shining upwards onto the arrangement. Different flowers have different watering needs, but since the water flows only accordingly as it is used up over or under watering is prevented. The use of a reservoir allows the flowers to be cared for while the owners are away.

Patent DE-2406860-A1 (DE)
Title: Oil pipe scraper feeding device - uses well head pressure rise to formation pressure for ball feed operation
Inventor: FALUCSKAI LAJOS DIPL ING
IPC: F16L55/46
Filed: 1974-02-13
Abstract: The paraffin layer deposited on the inside walls of a production pipe from the head of an oil well to a collector station is scraped off by introducing scrapers or hard rubber balls. Such a ball is introduced into the pipe by closing the pipe end temporarily so that the well head pressure builds up to the formation pressure and compresses a spring at the back of a piston. Retraction of the piston rod allows one ball to drop from a feeder branch into the pipe. This saves the necessity for any extraneous source of power for the operation of the scraper introduction device. This device is free from the risk of any failure in the extraneous power supply.

Patent DE-2411444-A1 (DE)
Title: Assembly line arrangement with storage effect - contains slide band, and weights on travelling tables
Inventor: SCHEFFLER HELLMUT
IPC: B65G47/26
Filed: 1974-03-11
Abstract: The working goods are transported on travelling tables with plates. The plates are moved via a moveably connected weight element, which due to its vertical load, causes friction adhesion to a slide band, moving continuously on a support surface. The friction adhesion is larger than the running resistance of rollers. This causes a drive moment of the weight element on the slide band, and the plate, at the line speed, until plate or band are stopped manually or by a barrier, and the band moves beneath the element. To increase friction, the weight may have a lining with a high coefficient of friction. The weight element may be replaced by a permanent magnet, with the slide band being of steel.

Patent DE-2417011-A1 (DE)
Title: Sensitive control for car heater - with hydraulic servo operating over large stroke for small temperature range
Inventor: SCHEURICH HANS-JUERGEN
IPC: B60H1/00
Filed: 1974-04-08
Abstract: The heater control has a hydraulic sensor linked to a connecting pipe which is coupled to a hydraulic servo. The servo operates a valve to control the flow of hot water to the heat exchanger. By making the heat sensitive part of the hydraulic system sufficiently large, small changes in temperature produce relatively large hydraulic volume changes. This provides a close control for the heat flow valve in that it fully opens for small changes in temperature. The heat sensitive element is covered by a vented knob whose setting determines the critical temperature at which the valve operates.

Title: Single sweep control for windscreen wiper - with thermal strip switch for simple reliable operation uses resistance heating of bimetallic strip
Inventor: JUNGWIRT REINHOLD
IPC: B60S1/08
Filed: 1974-11-23
Abstract: The wiper motor control circuit is used in road vehicles and it is fitted with a contact which operates the self parking sequence. In order to provide a simple, robust intermittent wiping circuit a bimetallic strip (6) is connected to the motor contact via the intermittent switch position. In this setting the motor current is broken at set intervals, with the motor contact moved to the self parking position. This prevents the wipers from being left in mid-sweep by the intermittent control. The rate of sweep sequences can be regulated by the characteristics of the strip, which is heated up when the current flows and cools down when the current is switched off.

Title: Screens against industrial traffic and similar noise - deflect sound on to sound- absorbing material or into open space
Inventor: JANUS JONNY
IPC: G10K11/20
Filed: 1974-12-02
Abstract: Noise-reflecting screens (12) are erected beside buildings, along motorways, etc., to deflect the unwanted sound on to a sound-absorbent surface, normally rough ground with vegetation cover, or into open space, normally the air overhead. Possible materials and forms for the screens are envisaged in profuse variety. Over 50 possibilities are offered, mostly of prefabricated concrete panels (12) leaning at an angle in slotted pedestals (11) or fitted into posts, but including, e.g. a vegetative screen created in a vertical stack of plant troughs. As the methods rely on reflection, the source of sound is assumed to be narrowly localised, as in a point (3) or line e.g. of motorway traffic.

Title: Ethylene recovery from gas mixt. - with separation of part of hydrocarbons contg. over three carbon atoms before methane sepn.
Inventor: SCHUSTER ROBERT
IPC: C07C7/04
Filed: 1975-02-11
Abstract: C2H4 recovery from a crude gas mixt. contg. hydrocarbons other than C2H4 takes place by compressing the crude gas mixt., cooling, separation, in several steps, into a 3+C hydrocarbon fraction, a CH4 and a 2C hydrocarbon fraction, and C2H4 separation from 2C hydrocarbon fraction. In new process, only part of 3+C hydrocarbons is separated before CH4 separation from crude gas mixt. in a pre-separation is separated in a further separation column, into a 3+C hydrocarbon fraction and a 2C hydrocarbon fraction. (i) Cooling requirement of process can be reduced by 32%. Head cooling temp. in both columns for 3+C hydrocarbons may be -20 degrees C (compared with -40 degrees C for temp. required in sharp separation of 3+C hydrocarbon fraction before CH4 separation), resulting in an 8% saving in energy requirement. (ii) Column for separating the last part of the 3+C hydrocarbons is arranged in shunt of process and is fed only with CH4 column sump fraction.
